2 Claims.

This invention relates to a container having a tubular body and a metal ring member secured thereto in an end scam, the ring member having an inwardly and upwardly extended annulus terminating in an edge defining the mouth of the container and has particular reference to a plurality of spaced transverse deformations in the annulus and spaced angular locking sections in the annulus for the reception of a metal cover which has a plurality of locking lugs cooperating with the angular locking sections of the annulus during a slight rotation of the cover for locking the cover in place thereon.

An object of the invention is the provision of a container having preferably a cylindrical container body with a metal ring secured to the top end thereof, the ring having an inwardly and upwardly extended annulus terminating in an edge and provided with a plurality of spaced transverse shallow and deep deformations alternately arranged to define spaced angular edge locking sections which are adapted to receive locking lugs of a metal cover, the cover being locked in place by a slight rotation relative to the body.

Another object of the invention is the provision in a container of the character described, of a frangible sealing disc, preferably secured to the top end of the container body by the metal ring, the metal cover having an annular wall overlying the metal ring with a countersunk panel or plu extending into the mouth of the container when the cover is applied thereto, the cover also having an outside depending skirt preferably terminating in a curled edge with corrugations in the periphery of the skirt to provide a hand grip for the application and removal of the cover.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure l is a perspective view of a container and cover disclosing a preferred embodiment of the present invention;

Fig. 2 is a top plan view of the container shown in Fig. lwith the cover removed;

- Fig. 3 is a vertical sectional view of the upper part of the container shown in Fig. 1 taken substantially along the line 33 in that figure;

Fig. 4 is a fragmentary view similar to Fig. 3 showing the cover in a different position;

Fig. 5 is a view similar to Fig. 3 and showing the cover in locked position on the container; and

Fig. 6 is a vertical sectional view of the upper portion of the container taken along the section line 66 in Fig. 2 and showing an angular locking section in the annulus of the upper metal ring member.

As a preferred embodiment of the invention the drawings disclose a container II, which includes a tubular body i2 made of fibre, metal or other suitable material having a metallic end secured to the bottom end of the body in a suitable end seam (Fig. 1). The top end of the body I2 is closed in part by a temporary sealing disc [4, made of cellophane, paper or other suitable frangible material which is adapted to be cut out to gain access to the container interior.

The frangible disc l4 may be held in place by an annular depending wall i5 of a metal ring l6 which is secured to the upper end of the body in a suitable end seam l'i (Figs. 3 to 6). The depending ring wall I5 extends inwardly and downwardly as an inclined circular wall I8, thence inwardly and upwardly to constitute an inclined upwardly extending annular wall 22, thereby providing a channel 23 therebetween. Wall 22 terminates in an upper inner periphery which is preferably formed with a rounded or hemmed edge preferably disposed in the same transverse plane as the end seam Ii. Obviously this edge may also remain a raw edge. The ring member wall 22 together with its edge will be hereinafter referredto as an annulus 24 defining the mouth of the container (see also Fig. 2).

An otherwise regular contour of the annulus 24 is altered at spaced intervals around its inner edge by depressing the metal at an angle to the horizontal between two spaced transverse shallow and deep deformations, depressions or indentations. Each shallow deformation with its associated deep deformation isolates or defines a depressed space in the annulus 24 setting it ofi as an inclined locking section 25 (Figs. 2 and 6) Four locking sections 25 are shown in the drawings. These may be more or less, depending upon the diameter of the container. Each section may be said to start at a lead-in end in the shallow deformation or indentation (as indicated by the numeral 26) and to terminate at the lower or opposite end in the deep deformation (as indicated by the numeral 21). The edge of the looking section at the shallow deformation 26 is pressed into depending cover hurdle element 32 (see Fig. 6) and at the deep depression 21 into a depending cover. stop element 33. These snaps and stops facilitate the application of a removable cover 34 for-the container and provide for the proper locking of the cover as will be described hereinafter.

The edge ofeach locking section 25 is arcuate but is not concentric with the inner unpressed edge of the annulus 24. This locking section edge is drawn inwardly to a smaller diameter. The making of the shallow depression 26. draws that end of the section edge inwardly a slightamount and the making of the deep depression 2! draws the terminal end still closer to the center of the ring as best seen in Fig. 2. This construction makes possible the locking of the cover 34 as will be clearly understood in the later consideration of the application of the cover to the container.

The cover 34 has an annular horizontal wall section 35 which is adapted to engage the upper surface of the end seam ll, with or without a sealing gasket interposed therebetween and also to rest upon or bridge the unpressed portions of the annulus 24 when the cover is applied to the container. This cover is formed with a countersunk central panel 36 disposed at the inner end of a depending surrounding inner cover wall 31 which extends down into the mouth of the container (Figs 1, 3, 4 and 5) inwardly of the annular cover wall 35. The depending wall 31 has a plurality of equally spaced outwardly extending locking lugs 38. There are four such lugs as shown in the drawings and these constitute the holding or locking means for the cover.

The cover 34 also has an outer depending skirt &2 extending from the annular wall section 35. This depending skirt projects down over and fully embraces the end seam ll when the cover is in closed position on the container. The skirt 42 terminates at its lower end in a preferably outwardly curled rounded or hemmed edge 43 (Figs. 1 and 5).

In applying the cover the locking lugs 38 of the cover are positioned directly over and just inside of the unpressed portions of the annulus 24. The cover is then lowered in place, the countersunk panel 36 passing into the mouth of the container. the distance between opposite lugs 38 is less than the diametric distance between opposed unpressed portions of the annulus so that the cover easily drops down with its horizontal wall seated on the end scam I! (Fig. 4).

The cover cannot be put on in the wrong position since the diametric distance between opposite inclined locking sections 25 of the ring is less than the over-all distance between opposed looking lugs 38. The locking of the cover takes place by a partial rotation relative to the container. In such rotation each lug 38 first snaps under the associated cover hurdle element 32 and then passes under the inwardly inclined locking section or thread until the cover is tightly locked in seating position on the seam I! of the container, with or without the aid of a sealing gasket.

This partial rotation of the cover must occur in the proper direction for should an attempt be made to turn in the wrong direction each stop element 33 on ring 24 would act as a barrier for the associated cover lug 38 and the lug would remain in the region of the unpressed edge portion of the annulus 24 and would not engage the inclined locking section 25 to lock the cover in closed position on the container. After the cover has been rotated sufficiently to pass a lug 38 under its associated cover hurdle element 32, the latter acting as a barrier will prevent accidental reverse rotation which might otherwise result in loss of the cover.

In order to facilitate the'rotation of the cover during its application onto the container and during its removal therefrom, corrugations or knurling 44 are formed in the periphery of the cover skirt 42 (Figs. 1, 3, 4 and 5). These corrugations thus assure a firm hand grip on the cover.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may bemade in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
